  1. Note: N = number of observations, given by 59 controls and 44 patients with schizophrenia making 10 decisions in each task. As each participant is interacting individually with an artificial agent, we cluster the standard errors by individuals, so that the total number of clusters are 59 and 44 respectively. P-value: *** < 0.1%, ** < 1%, * < 5%.
